HTML5 APPLICATIONS DEVELOPMENT MANUAL

The WinRT works with C#, C++, Visual Basic, and JavaScript. You

can build Metro style apps with the WinRT and Windows Library for

JavaScript APIs. An application programming interface (API) is simply a

list of instructions letting a program communicate with another program. In a

Web app, an API enables a Web browser or a Web server to communicate

with other programs. There are hundreds of APIs available for many different

uses.

The Document Object Model (DOM) is an important API to keep in

mind. The DOM is designed for HTML and Extensible Markup Language

(XML), and allows programs and scripts to update content, structure, and

styles on the fly - essentially anything in an HTML or XML file can be

modified. The DOM is neither HTML nor JavaScript, but it ties them

together.
